OBD or Cable
 

03 TJ - Question is does it have Electronic Speedometer or a Cable. I cannot locate the cable so I am presuming its Electronic, but I need to know for SURE. I have no abs if that helps in repling. Also has anyone had the speedometer adjusted after a gear change? Any in put or is that out put whatever wud be appreciated.

your speedo is electric,aftermarket speedo converters (not sure exactly what there called)are available,if you have a 231 t case you can pull the speedo gear out of t case and replace with one with different amount of teeth.several different gears were used in various models depending on engine,trans,rear axle gearing etc.hope this helps do a google search on correcting TJ speedometer
